IRRIGATING APPARATUS.

Application led October 26, 1921'. Serial No. 510,634.

This invention relates generally to irrigating apparatus and has as its main object a simple construction in which the water used for irrigating purposes is likewise used for the slow turning of one or more irrigating pipes and for automatically reversing the turning movement of said pipe, the construction also embodying simple means for varying the rate of flow of irrigating water and the speed of oscillation of the pipe.

Other objects and features of construction will appear as the specification proceeds.

Fig. 13 is a horizontal sectional View on Athe plane of line 13--13 of Fig. 12.

Connected with` an upright pipe 1 is a.

power unit 2 through which the irrigating water passes to the horizontal oscillating sprinkler pipe 3.

Said power unit' comprises essentially a main duct 4 on one side of which, preferably the outer side, is arranged a rotary water motor 5, the casing 6 of which is bolted to the main duct at 7, preferably'in such manner that shaft 8 of the water motor passes at one side of the main duct, the water motor being located in a branch duct 9, connected with the main 'duct at the upper and lower end thereof, the` two ducts forming a head at the .upper end of the structure. 10 is a valve interposed inv the main duct and 11 is a valve interposed in the branch duct.

12 is a stationary pipe extending in a horizontal direction from the power unit and forming a continuation of the lducts thereof and is in constant Communication with the sprinkler pipe 3,' there being a joint (Fig.

la) formed by means of the globe 'member 13, into which the end of pipe 3 is threaded, and collar 14 threaded on said globe inember and rotatably mounted on pipe 12. It will be noted that the en'd of pipe 12 extends into the globe member and that a ypacking 15 is employed to form a tight joint. Carried by sprinkler pipe 3 and preferably mounted on globe member 13 by meansof bracket 16 is a gear sector 17. This sector has a single set of internal teeth facing both ways, and carries two pins 18 that may be positioned, asshown, near the extremity of said sector or at someV intermediate point indicated at 19, 'depending upon the extent of oscillation of pipe 3 desired.

Mounted loosely on pipe 12 and intermediate collars 14 and 20 is a swinging arm 21 provided with a p-ivota-lly supported pawl 22 engaging sector 17. Suitable means for rocking said arm are provided, here taking the form of a. crank pin 23 carried by crank member 24 on shaft 25, the crank pin engaging in the elongated slot 26 of arm 21. Shaft is suitably supported as by means of bracket 27 bolted at 28 tothe .main duct `on that side which is opposite to theone on which the water motor is located and its axis is parallel to the axis of said water motor. Suitable reduction transmission means are interposed between sha-ft 25 and shaft 8 consisting here of a train of gears including pinion 29 on shaft 8, spur gear 30 and pins 31 on shaft 32 carried by the main duct, spur gear 33 and pins 34 carried by shaft 35 of the main ductnnd spur gearlttoneshalttff. 37 is an extension forming a. 'handle by which the oscillating pipe may be adjusted or set by hand.

It Will be understood that rotation of the Water motor causes, through the train-0f reduction gears mentioned, rotation of crank pin 23 and thereby oscillation ott arm 21. Pawl 22 is thereby so actuated that, when moved in one direction (to the left in Fie. it), it carries sector '17 with it.; and, when actuated in the other direction (to the night in Fig. 4;), said paul, owing to its pivotal connec'tion on arm 21, will ride over one 'tooth Without turning the sector. *In this manner pipe 3 willbe turned, step -by step, until pand 22 strikes pin 18 a(asin Fig. 54) when 'its position is reversed and the continued Inove- .lnent of crank pin 23 will then rpull the sector back, step by step, lin the opposite direcltion until the otherpin 18 is reached. Tf it is desired to deereasethe extent of the oscillation of pipe 3, pin 18 is inserted in .another hole such as 19.

'llhis invention is an in'iprovenlcnt .in the construction shown in Patent No. 51,112,271 .and .to .prevent lbackward rotation of the sprinkler pipe, the saine supporting'means as is `.shown in Fig. L6 of Ithat Apatent .may be employed.

Usually the amount o'f water supplied to the sprinkling ipipe .and the speed of motor 5 will be regulated 'by adjusting va'lve 10, the :speed of the motor being increased .and :the amount of the Water supplied directly to sprinkler ,pipe beineV decreased 'by partially closing valve 10 andi conversely, :the speed of the motor being diminished and the amount of water supplied directly to *the sprinkler pipe `being increased by opening valve 10 more widely. :Since, however, the water from the motor returns to the `main circuit, the effective result will be a varia.- tionof motor speed, and Ahence oscillation of 'the sprinkler pipe Without la variation of the amount of water. Itt it -is desired to vary the motor speedttoagreat nicety, val-ve 11 may be actuated to vary :the amount o water supplied .to `the motor.

Inl Figs. 6 and 7 is shown a modiiedcon- .struction in Which 'the 'head '38 vterminating the Ativo ducts is oit T formation and open .at both sides. Oscillatory .sprinkler pi-pe 39 extends clear through .this 'zhead .and has swivel connection therewith, :there being a suitable packing as 40 at each end and cdlilars t1 `to prevent endivise displacement. 'Pipe 39 has openings 42 by :means .of which 'Water flows fromthe ducts orfhead into the sprinkler lines. Gldbe member 43 is, in ltliis instance, -rigid on pipe 39 and is devoid of .any swivel joint, lservingmerely as a supjport for extensionor`handle`37-and for 'gear Vsector 17. The effect of this Aconstruction is to produce two oscillatory sprinkler lines in axial alinenientiind movable in unison and controlled from a singlehandle.

l slight modilication ot' the mounting of" the oscitlitting wrm that carries the pawl is also shown in these ligures. As here shown, arm 44, `instead of being hung on pipe 3! is pivotally supported Yat l5 on l ncket 27. The gearing is otherwise exactly the same asin Figs. 1 to 5.

[ln Figs. 8. t) and it) are shown a second ,modified .forni oli' the invention. ln tliis'construction .the power unit terminates at its upper end in a 'head 46 open at both sides into which are screwed stationary pipes 47 and .48 and connected to each of these stutionary pipes is-an oscillatory sprinkler pipe t9 and 5t); the .connection .being made by means-of aswivel joint 5l or 52 similar to` the .member 14 in Fig. l and each provided with a separate operating handle ,53 or 54. The gearing here is the same as in Fig. 1, except .that the `crank shaft 55 extends through the casing of the power other side thereof. where it 'is supported "by a lsecondln'acket 5G. bolted to the casing, and is provided at that end with a crank 57 en gaging a slot in oscillatory arm 58 pivot-ally supported at -59 and pivotally supporting a reversible pawl 6()engaging .a gear sector 61 carried liyvextension 54. By this meansLtWo Vindependent sprinkler lines .can be oseillated together orindependently of each othertrom the same motor. If it is desired to `silence one of the sprinkler lines, the crank or the pawl or some other part may be vremoved or valves that may be located 'in pipes 4:7 and 48 or 49 and '50 (but not shown) maybe closed, or a vilve may be closed and say a paw] re moved or rendered inactive. Furthermore, by lpositioning ypins 18 of one sprinkler line ydifferently from those of theother, different arcs offoscillation -oi the two coaxial sprinklei' Alines maybe produced.

'times difficulty ,is experienced 1n properly spacing pawl ivi'th respect to sector 1-7because of the diliculty to always screvvr pipe 12 into the power unit a predeterminedwdistance. To overcome this diliicnlty gear sector 17 is carried "by a bracket 62 which "is adjnstably mounted by reason of bolts '63and slots 64 on member 65 forming a part of a clamp surrounding extension 37. In :Fig: 11 oscillating arm 21 is shown mounted as in Fig. 1, but it willbc understood that 'it -Jnay be mountedas in Figs. 6 or 8.
